The beneficial effect of this practicality is: the SF described in this practicality
6sensing device, forms a structure sealed by housing and electric conductor, by the situation of excessive water content in the principle of reflection checkout equipment of plane mirror and infrared light, this device not only structure is simple, detects rapidly, easy to use, and need every year to every only micro-water sensing equipment effect, also without the need to extracting SF out
6the micro-water of gas detect, avoids SF
6the pollution of the severe environments that direct discharge causes air.
Accompanying drawing explanation
Fig. 1 is the structural representation of this practicality;
Fig. 2 is the side view of Fig. 1;
Fig. 3 is the structural representation of turnover joint.
Detailed description of the invention
Below in conjunction with accompanying drawing, this practicality is further described.
As shown in FIG. 1 to 3, the SF of the present embodiment
6electric equipment light path sensing device, comprise the sensing body 1 be set on electric equipment electric conductor 2, sensing body 1 by the hollow cylindrical of both ends open housing 11 and be located at housing 11 both ends open place respectively and form for closing the insulated enclosure plate 12 of this opening, insulated enclosure plate sealing plate 12 center at housing 11 two ends is arranged with electric conductor patchhole, this sensing body 1 to be enclosed within electric conductor 2 by patchhole and to form a space sealed with electric conductor 2, is full of the SF of certain pressure in the space of sealing
6gas, this SF
6gas mainly plays insulation, arc extinguishing and cooling effect.A hole is opened in any end of housing 11, for installation infrared light turnover joint 3, turnover joint 3 offers infrared light light well 31 and infrared ray light hole 32; Be respectively equipped with multiple atomic facet mirror 4 at housing 11 and the junction of its two ends insulated enclosure plate 12, this plane mirror 4 by fused quartz glass photoscope by making at its electrosilvering film.Infrared light is injected in housing 11 by light well 31, IR can be made to shroud whole housing 11 inner space, and penetrated by light hole 32 after plane mirror 4 reflects; Be respectively equipped with in light well 31 and light hole 32 for sealing this light well 31 or light hole 32 with the diaphragm seal 5 preventing housing 11 outside moisture from entering its inside.
Turnover joint 3 is made up of the upper plate body 34 and lower body 35 being mutually fixed connection, and upper plate body 34 and lower body 35 are made by insulated enclosure resin plate; Non-aging insulation silica gel material is provided with between upper plate body 34 and lower body 35; Diaphragm seal 5 is circular quartz glass manufacture, and between upper plate body 34 and lower body 35, be provided with the installing hole installing this quartz glass, quartz glass is embedded in this installing hole.
Conveniently IR is entered by light well 31, the IR entered can be made to shroud whole housing 11 after plane mirror 4 reflects, and penetrate through light hole 32, its light well 31 and light hole 32 relative tilt are arranged in the present embodiment, this angle of inclination with 45 degree for benefit.
Because the electric conductor 2 of electric equipment is longer, in use, need multiple housing 11 to be connected in series and be arranged on electric conductor 2, interfixing conveniently between housing 11, be provided with multiple bolt mounting holes 7 in the side of sensing body 1, interfixed by flange and bolt between this housing 11 and housing 11.Infrared light is injected in housing 11 by light well 31, is mutually reflected by the plane mirror 4 in housing 11, forms one shroud shape, by electric conductor 2 and SF to make this IR in housing 11
6gas cover as much as possible into, facilitate the detection of micro-water in housing 11; It is outside that light after plane mirror 4 reflects finally penetrates housing 11 by light hole 32.
Dotted portion in Fig. 1 is IR reflected ray.This device not only structure is simple, detects rapidly, easy to use, and needs every year to every only micro-water sensing equipment effect, also without the need to extracting SF out
6the micro-water of gas detect, avoids SF
6the pollution of the severe environments that direct discharge causes air.
Above-described embodiment is only be described the preferred embodiment of this practicality; not the scope of this practicality is limited; under the prerequisite not departing from this practical design spirit; the various distortion that the technical scheme of those of ordinary skill in the art to this practicality is made and improvement, all should fall in protection domain that these practical claims determine.
